why can only massive stars form black holes ? ( describe )
the natural consequence of the evolution of massive stars. Neutron stars have an upper mass limit of 2 to 3 solar masses. A collapsed object of greater mass will continue to collapse indefinitely, forming a black hole.
The inevitable result of the development of enormous stars. The maximum mass of neutron stars is 2 to 3 solar masses. A more massive collapsed item will keep collapsing forever, eventually creating a black hole.
What is a Black hole?Space-based black holes are regions of extreme density that produce large gravity wells. Even light cannot escape the strong pull of a black hole's gravity once it reaches a specific area. And in a theorized process fittingly known as spaghettification, anything that gets too close, be it a star, planet, or spaceship, will be stretched and squished like putty.
According to the question, A supernova is a star that explodes brightly when it is dying. A supernova can happen when a star loses heat at its core, causing it to eventually collapse. This kind of supernova results from the death of huge stars. They take place in galaxies with active star formation and an abandoned black hole or neutron star.
Supernovae can also happen when one star collides with another as it orbits another. In a white dwarf, this happens. This can happen in a very old star cluster, which is a component of a binary system and leaves no compact object in its wake.

Both strands of the DNA double helix contain nitrogenous bases held together by hydrogen bonds. In DNA, the sequence of nitrogenous bases varies widely. What is the significance of the nitrogenous bases? (6A) Question 4 options: They determine the amino acids in the proteins synthesized. They prevent mutations from occurring in the process of DNA replication They help complete the sugar-phosphate backbone of DNA molecules. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.
Answer: They determine the amino acids
Explanation: The sequencing of the bases directly code for the amino acids. If anything changes, it would change the code, and could possibly create a different gene all together.
The significance of the nitrogenous bases is that they determine the amino acids in the proteins synthesized.
DNA:
Deoxyribonucleic acid is a biological molecule that stores genetic information in living cells. DNA is a polymer made up of monomers called nucleotides. In the nucleotide subunits of DNA, nitrogenous bases are one of the components. The sequence of nitrogenous bases in DNA molecules varies from one another. This is because the sequence determines the sequence of amino acid that will form proteins when translated.

Analyze the graph below and identify the points where the population is stable at the carrying capacity.
Answer:
To find carrying capacity on a graph, you need to locate the point on the graph where the population line is horizontal. Alternatively, the carrying capacity may be explicitly marked with a dotted horizontal line or a horizontal line of a different color.
Explanation:
i dont know if this is right but hope this helps
The carrying capacity on a population growth graph is the level at which the population stabilises and achieves equilibrium as a result of the environment's resources.
What is the reason for the equilibrium ?This equilibrium happens as a result of the population curve plateauing as the limiting elements, such as food, water, and space, start to restrict the population's ability to grow.
The carrying capacity is symbolised graphically by a horizontal line on the graph, signifying that the population has reached its limit and cannot grow any further.
This horizontal line can be clearly identified on the graph by a dotted line or a different colour. Alternatively, the population line's horizontal intersection with the point where it stops growing can be used to determine the carrying capacity.
A constant condition of population has been reached.
It is crucial to remember that a population's carrying capacity can alter over time owing to a variety of variables, such as changes in the climate or improvements in technology that make resources more accessible.

Why it is important to have a standard unit measurement system?
Answer:
because it allows scientists to compare data and communicate with each other about their results.( Metric System )
Explanation:
1. In the system shown below, there are 80 x particles, all in region A (the left half of the box). No extra particles can enter the system. When the system is in
equilibrium, what will be true of the particles?
A Since there are no y particles, the system is already in equilibrium with ail 80 x particles in A
B. Due to the constant motion of particles, this system will never reach equilibrium
C. In equilibrium, there will be exactly 40 x particles in A and 40 x particles in B, and those numbers will remain constant
Din equilibrium, there will be approximately 40 x particles in A and 40 x particles in B, and those numbers will fluctuate but will remain near 40
Answer:
The correct answer is - option D. in equilibrium, there will be approximately 40 x particles in A and 40 x particles in B, and those numbers will fluctuate but will remain near 40.
Explanation:
Equilibrium is the condition where all the condition is where all the factors or influence forces are balanced in a particular system. The perfect balanced condition is not easy to get or can not remain constant for long.
In this example, both A and B get 40 x particles to be in equilibrium however fluctuation persists but still approx 40 remains.
Thus, the correct answer is - option D

What is Cellular respiration?Cellular respiration is the process through which the biological fuels are oxidized in the presence of an inorganic electron acceptor such as the oxygen atom to produce large amounts of energy, to drive the bulk production of ATP (adenosine triphosphate) in the mitochondria.
The purpose of cellular respiration is to provide the body cells with the energy which they need to function. If living things could not get the energy which they need out of food, it would be absolutely worthless for them. All living things would eventually die, no matter what the quality and amount of food.
Therefore, the correct option is C.

Use the words haploid cell, diploid cell, and fertilization all together in a sentence.
Answer:
The sexual life cycles involve the alternation between meiosis and fertilization. Meiosis is a process where the diploid cells gives a rise to haploid cells, and fertilization is the process where two haploid cells (gametes) fuse to form a diploid zygote.
Explanation:
Hope this helps
Using the words haploid cell, diploid cell, and fertilization all together in a sentence - Fertilization is the union of two unicellular, haploid gametes to produce one unicellular, diploid zygote.
The process of combining the male gamete, or sperm, with the female gamete, or ovum. The product of fertilization is a cell called a zygote.
Fertilization takes place when two haploid cells fuse together such as sperm cells and egg cells.Haploid cells have a single set of chromosomes.The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes that fuse during fertilization.Diploid cells are a cell that contains two sets of chromosomes that are formed after fertilization also called a zygote.Thus, the correct sentence would be - Fertilization is the union of two unicellular, haploid gametes to produce one unicellular, diploid zygote.
